James Watson, the legendary scientist who co-discovered the double-helix structure of DNA and helped ignite a revolution in biology, has died at age 97. Watson’s death on November 6, 2025, in East Northport, New York, marks the end of an era for molecular biology—a field he helped define, but also one shadowed by his later controversies.
The Double Helix Breakthrough That Changed Everything
At just 24, Watson—alongside Francis Crick—unveiled the iconic twisted-ladder structure of DNA in 1953. This discovery, which earned them the 1962 Nobel Prize in Physiology or Medicine (shared with Maurice Wilkins), instantly transformed our understanding of genetics. The double helix became a universal symbol of science, inspiring everything from medical breakthroughs to pop culture references.
Watson’s insight revealed how genetic information is stored and copied, laying the groundwork for everything from gene therapy to forensic DNA analysis. As Bruce Stillman, president of Cold Spring Harbor Laboratory, put it, the discovery ranks among “the three most important discoveries in the history of biology,” alongside Darwin’s theory of evolution and Mendel’s laws of genetics.
A Towering Career—and a Tumultuous Legacy
After his Nobel-winning work, Watson shaped the future of science education and research. He built Harvard’s molecular biology program and, as director and later president of Cold Spring Harbor Laboratory, transformed it into a world-class research center. He also played a pivotal role in launching the Human Genome Project, ensuring that ethical questions were part of the conversation from the start.
But Watson’s legacy is complicated. In 2007, he made widely condemned remarks suggesting genetic differences in intelligence between races—a view denounced as racist by the scientific community. The backlash led to his resignation from Cold Spring Harbor Laboratory and, in 2019, the removal of his honorary titles after he reiterated his views in a PBS documentary.
Personal Life and Final Years
Watson was known for his brash personality and unfiltered opinions, both of which contributed to his scientific success and public controversies. He married Elizabeth Lewis in 1968 and had two sons, one of whom, Rufus, has schizophrenia—a fact Watson often discussed to advocate for mental health research.
In his later years, Watson remained a polarizing figure. He auctioned his Nobel Prize in 2014, donating the proceeds to educational causes. He was also one of the first people to have his entire genome sequenced and made public, underscoring his lifelong commitment to advancing science.
What Watson Leaves Behind
Watson’s death has prompted reflection across the scientific world. The New York Times called him “one of the most important scientists of the 20th century,” while the BBC noted that his work “opened the door” to modern molecular biology—even as his personal views sparked ongoing debate about the responsibilities of scientific leaders.
His story is a reminder that scientific genius and personal failings can coexist—and that the impact of discovery can echo far beyond the laboratory.
